Where can I find the supporting documents for UL approval of the MP2000 controllers?

Posted Date: 02/04/2011

Answer:

UL has what they call their "yellowcard" which is their listing of all the products that are UL Recognized or Listed in a given file.

This information is available online by searching for the appropriate file number in UL's online certifications directory at: http://database.ul.com/cgi-bin/XYV/template/LISEXT/1FRAME/index.html The file number is E184524.

All error codes will appear at the MCFG_Yaskawa AOI. There are separate fields for servopack alarms, controller alarms and application error codes. For a more verbose description, look in the controller tags at 'AxisRef'.I.AlarmText.

When using the analog output function on a GPD506/P5, how is the output scaled when output current is selected?

Posted Date: 06/12/2014

Answer:

The 0-10Vdc output is scaled to 0-100% of the drive rated current. Parameter n052 is used to setup the drive for output current monitoring and n053 sets the analog monitor gain value. For example, if the user wants 0V= 0% and 3V=100%, then use formula n053= Desired voltage @ 100% drive output rating/ 10V. For the above example, n053= 0.3 (See graph attached).

When using SMC-2000 analog input, where is the ground (common) signal connected?

Posted Date: 05/22/2001

Answer:

The SMC-2000 analog I/O (I/O1 connector) uses the same ground reference as the internal 5V (control logic) power supply. Therefore, any 5V ground connection (such as AE1-pin23 or AE2-pin23) can be used as a ground reference for the analog input. It should be noted that the analog I/O is optically isolated from the 24V digital I/O.

When using SigmaWin software, what are the units when graphing torque?

Posted Date: 07/13/2004

Answer:

When using a matched Servo Pack / Servo Motor combination (eg. SGDH-05xx, SGMGH-05xxxxx) the units are percentage of rated torque.

Sigma II allows (for emergency situations) operation of the Servo Pack / Servo Motor combinations of up two times larger or one-half smaller. This affects the units of the torque monitor by displaying the percentage of rated torque for the lowest rated component. For example:

If an SGDH-05xx and an SGMGH-09xxxxx were combined, the display units would be percentage of rated torque (current) for the SGDH-05xx.

If an SGDH-10xx and an SGMGH-05xxxxx were combined, the display units would be percentage of rated torque (current) for the SGMGH-05xxxxx.

When using MotionWorks+, is there a way to tell which version of a project is currently in the RAM memory of the MP940 and the last date it was revised?

Posted Date: 07/13/2004

Answer:

If revision data is needed, it can be managed by generating three CONSTANTS in the MW+ project file: Year, MonthDay, and RevisionNumber. This technique is a common practice among MW+ programmers to consistently maintain revisions.

Constant Definitions:"Year": Assign to the initial value of this constant, the year the project was downloaded."MonthDay": Assign to the initial value of this constant the month and the day the project was downloaded. If the project was downloaded on March 17th , the constant would be 3.17"Project": Project Number.Revision level - If project number 176 with a revision level of 4 is in the memory, the constant value would be assigned as 176.004

Assign the appropriate data to the initial value to these three constants. By using the data monitoring feature in MW+, the revision number can be seen. Using this method, it is important to remember to change the revision data manually every time a significant change to the project is made. There is no automatic update.

To retain each revision, be sure to save any changes as a new project.

For the case of axis 1: In order to initiate the read OBC000A (Absolute position read request) must transition from OFF (0) to ON (1.) The confirmation flag that the read is complete is IBC000A (Absolute read complete signal) will transition from OFF (0) to ON (1.) If there is a problem with the absolute read, then IBC0004 (Cumulative number of rotations error) will transition from OFF (0) to ON (1.)

The OBC000A (Absolute position read request) should not be ON (1) in the "setting parameters." This bit will initiate the absolute encoder read, and is dedicated for the application program. If the Servopack loses control power but the MP920 does not, then the OBC000A (Absolute position read request) bit will have to be toggled OFF then ON again for a re-read of the encoder's absolute position. The application program can test if the Servopack's Control is ON by monitoring the state of the "Broken PG Wire" bit; IBC00232.

Please reference section 5.7 in the "Sigma II Series Servo Manual" (YEA-SIA-S800-32.2) for details on how the absolute encoder data transfer works.

When using an absolute encoder, is it possible to set the absolute zero position through the Fieldbus Network?

Posted Date: 01/09/2002

Answer:

An absolute encoder reset must be done to clear the A.81 alarm. For safety reasons, this can only be performed through the SGDH front panel with a Function 8 or through the monitor software. This operation is typically only performed at machine startup when the mechanical system is coupled to the motion control system.

Once the absolute zero is set, a new zero point can be established over the Fieldbus Network for the convenience of the user. Define the new zero point by using the Define Zero Point Command in the Set/Read section of Command/Response format - Section 5.3 of the NS300 User Manual.

When using 2 option cards, I am receiving an OPE06 fault and am not seeing all the F1 parameters. I am using CN5-B for my encoder feedback card.

When the personal computer (PC) serial port connection is disconnected from the controller, why does the SMC-2000/3010/4000 controller become unresponsive?

Posted Date: 07/13/2004

Answer:

The SMC-xxxx products use hardware handshaking, and if there are commands in the program that send unsolicited messages (MG, IN commands) they are transmitted from the default port. The serial port is the default port. The apparent "lock up" is caused when no device connected to the serial port. (The controller sends a character and waits for the hardware handshaking signals before it can continue to the next command.)

Since MG commands are typically used for debugging. These messages can be removed and the "lock up" will no longer occur. However, when it is preferred to leave the debugging messages in the program for use at a later time, there are at least three methods for handling this.

1) Use search & Replace to change all MG command into NOTE: MG2) Create a user variable such as "DEBUG" in the program.

Use this variable in the program prior to writing any MG message command.Be sure to initialize it to zero whenever power is cycled; such as DEBUG=0

#AUTODEBUG=0

Use DEBUG in the program with the MG commands:

IF (DEBUG=1) MG"WAITING FOR HOME SIGNAL"ENDIF

All three lines above can put the in one line to save program space, the SMC controllers allow 80 characters per line.

IF (DEBUG=1); MG"WAITING FOR HOME SIGNAL"; ENDIF

This will skip the messages while DEBUG=0. When connected online with the PC, type DEBUG=1 in the terminal window and debug messages will again be displayed. Prior to going offline, either set DEBUG=0 from the terminal or cycle power.

3) Messages can be diverted to an unopened Ethernet handle without causing an error or lock up. Use the CF command to send messages to an Ethernet handle.

Note: When connecting to an SMC-3010 or SMC-4xxx controller via Ethernet, Yterm automatically sets the default port (CF Command) to the handle on which the connection was made. When the BN command is executed, the default port is one of the configuration settings that are saved. Make sure to include any important configuration setting in the program to avoid confusion about the actual value of the parameters.

4) The last, and least elegant solution is a jumper plug for the SMC serial port. This plug would connect the RTS and CTS pins; effectively making the controller believe that hardware handshaking is connected and working.

When setting parameter Pn300 (Speed Reference Input Gain) what rated speed should be used for Linear Motor applications?

Posted Date: 07/13/2004

Answer:

The configuration of Parameter Pn300 is the same for Linear Motor applications as it is for Rotary Motor applications. The motor speed is controlled in proportion to the input voltage between V-REF (CN1-5) and SG (CN1-6). This is depicted in the attached .PDF file that includes graphs and setting examples.

For further information regarding adjustment of parameter Pn300, refer to the Sigma II Series Servo System User's Manual [YEA-SIA-S800-32.2] section 5.2.1.
